Clinical Trial Summary

Total colectomy with ileorectal anastomosis is a traditional surgical option for slow transit constipation. Subtotal colectomy with caecorectal anastomosis is suggested to be a superior approach. However, the optimal surgical option for slow transit constipation (STC) is controversial.

Description:

Constipation is an ever-growing problem and one of the most common gastrointestinal symptoms, affecting 10-15% of adults in the USA and 8.2% of the general population in China. Slow transit constipation(STC), representing 15~30% constipated patients, is characterized by a loss in the colonic motor activity. Factors such as increasing age, female sex, physical inactivity, endocrine,metabolism, neurological factors, drug use, and depression are associated with constipation. While most patients with constipation are mild and treated easily by a behavioral and medical way, a minority of patients suffering from long-term intractable symptoms and poor quality of life and showing no response to any medical interventions are ultimately recommended for surgery.Since the effectiveness of colectomy for constipation was first reported by Lane a century ago, surgical treatment for constipation has been greatly developed, including ileorectal anastomosis (IRA), cecorectal anastomosis(CRA), colonic exclusion, antegrade enemas (the Maloneprocedure), modified Duhamel surgery, and permanent ileostomy. Currently,the main surgical procedures for STC are total colectomy with ileorectal anastomosis (TC-IRA) and subtotal colectomy with caecorectal anastomosis(SC-CRA), which have been widely confirmed to increase bowel-movement frequency in a huge number of patients. However, TC-IRA is a traditional surgical option for slow transit constipation. SC-CRA is suggested to be a superior approach. However, the optimal surgical option for slow transit constipation (STC) is controversial.This study aims to compare TC-IRA versus SC-CRA for STC with respect to the short- and long-term defecation function and overall quality of life during 3-year regular follow-up.

Intervention

Procedure:
• subtotal colectomy with cecal-rectal anastomosis
The intervention involves, after a complete mobilization of the colon, a resection 2-3 cm distal to the ileocecal junction and at the upper part of the rectal ampulla; the cecum is then lowered into the pelvis, without any rotation, and an antiperistaltic cecorectal anastomosis is performed between the cecal fundus (after appendectomy) and the rectum, after introduction of a stapler through the cecal resection line. In the laparoscopic approach we use 5 trocars (trocar 1 periumbilical, trocars 2-3-4-5 drawing a 15-cm side square around trocar 1), using a Pfannestiel incision to perform the anastomosis and to remove the resected colon. The cecal-rectal anastomosis is performed by introducing the stapler via the anus, with the intention of carrying out a ''cleaner,'' ''tensionless'' procedure.
• total colectomy with ileorectal anastomosis
After a complete mobilization of the colon, a resection 2-3 cm proximal to the ileocecal junction is conducted. Use a Pfannestiel incision to perform the anastomosis and to remove the resected colon. The ileorectal anastomosis (end to end) is performed by introducing the stapler via the anus, with the intention of carrying out a ''cleaner,'' ''tensionless'' procedure.
